Movies: "Paranormal Activity" (2009), "Paranormal Activity 2" (2010), "Paranormal Activity 3" (2011), "Paranormal Activity 4" (2012), "Paranormal Activity: The Marked Ones" (2014)Upcoming movies: "Paranormal Activity: The Ghost Dimension" will open on October 23, 2015.Why: The first "Paranormal Activity" was a damn good low-budget horror flick that felt like a refreshing antidote to the depressingly gory (and just plain awful) "Saw" sequels then dominating the Halloween-season release schedule. Unsurprisingly, Paramount saw mad dollar signs and proceeded to greenlight a follow-up every single year, though audience fatigue could finally be seen with "Paranormal Activity 4," which brought in only about half of what its predecessor managed at the U.S. box-office. Still, $142 million worldwide is a whole hell of a lot for a film that cost only $5 million to produce and even the $91 million for "The Marked Ones" isn't bad. But every gravy train must reach the end of the track eventually, and if the box-office downslide continues we may finally be rid of a series that has long since passed its sell-by date.
